One of two iterators for class RWDlistCollectables. As a const
iterator, this iterator does not contain any functions that change the data structure it is iterating through.
This iterator traverses the linked-list from the first (head) to the last (tail) item. Functions are provided for moving in either direction.
As with all Rogue Wave iterators, the "current item" is undefined immediately after construction – you must define it by using operator()() or some other (valid) operation.
Once the iterator has advanced beyond the end of the collection it is no longer valid – continuing to use it brings undefined results.

Constructs an RWDlistCollectablesConstIterator from an RWDlistCollectables. Immediately after construction, the position of the iterator is undefined.

Constructs an RWDlistCollectablesConstIterator from an RWDlistCollectablesIterator. Immediately after construction, the position of the iterator is undefined.

inlinevirtual |
Moves the iterator to the next item which isEqual() to the item pointed to by target and returns it. If no item is found, the function returns rwnil and the position of the iterator is undefined.
Implements RWConstIterator.
|
inline |
Moves the iterator to the next item that is identical to the item pointed to by e (that is, that has address e) and returns it. If no item is found, the function returns rwnil and the position of the iterator is undefined.
|
inlinevirtual |
Returns the item at the current iterator position.
Implements RWConstIterator.
|
inlinevirtual |
Advances the iterator and returns the next item, or rwnil if the end of the collection has been reached.
Implements RWConstIterator.
|
inlinevirtual |
Resets the iterator. Afterwards, the position of the iterator is undefined.
Implements RWConstIterator.
